TPU found pictures of the ASRock Z77E-ITX motherboard at Lab501.ro, a new Z77 based motherboard with a Mini-ITX form factor. There's room for two DDR3 modules, one PCI Express 3.0 x16 card, and one mini-PCIe 2.0 x1 card. Onboard are two SATA 6Gbps and two SATA 3Gbps connectors, one eSATA 3Gbps, DVI, HDMI, DisplayPort, 8-channel HD audio, Gigabit Ethernet, and six USB 3.0 ports.
The board makes good use of its scarce PCB real-estate, with a 6-phase VRM powering the CPU, two DDR3 DIMM slots that support dual-DDR3 2800+ MHz by overclocking, one PCI-Express 3.0 x16 expansion slot, a mini PCIe 2.0 x1 slot (for wireless cards) and lots of connectivity. With storage, there are two SATA 6 Gb/s and two SATA 3 Gb/s internal ports, and one eSATA 3 Gb/s. With display, there's one each of DVI, HDMI, and DisplayPort. 8-channel HD audio gigabit Ethernet, six USB 3.0 ports (4 back, 2 front), make for the rest of it.
